Problems solved by technology

However, due to the fact that the sample is in a static state in the freezer substitution instrument, the replacement speed of the organic solvent and the water in the sample is slow at low temperature, resulting in a long experiment period of freezer substitution, which usually takes 5 to 7 days, and it is difficult for plants, yeast, etc. to permeate Samples take longer, which not only makes the use of the instrument inefficient, but also greatly limits the speed of experimental progress

Abstract

The invention relates to a shaking table device which comprises a shaking table for carrying a sample, a sample chamber cover, and a shaking table driving device; and the shaking table driving device is arranged on the sample chamber cover, is connected with the shaking table through a connecting piece passing through the sample chamber cover, and is used to drive the connecting piece movement to drive the shaking table to shake. The shaking table device provided by the invention can increase the penetration velocity of a replacement liquid by cooperation of the shaking table driving device and the shaking table, and can greatly shorten the replacement time of the replacement liquid.

Description

technical field [0001] The invention relates to the technical field of biological experiment equipment, in particular to a shaking table device. Background technique [0002] Freeze substitution, as one of the methods of sample preparation for bioelectron microscopy, is currently widely used in the study of cell ultrastructure. Conventional sample preparation methods are chemical fixation and dehydration at room temperature, which can easily cause the loss and redistribution of some soluble components and some biomacromolecules, resulting in changes in cell structure, so it cannot meet the needs of people studying tissues and cells at the molecular level. Ultrastructural requirements. The basic principle of the freeze substitution method is to slowly replace the solid water in the fast-frozen (such as high-pressure frozen) sample with an organic solvent at a low temperature, and at the same time assist with chemical fixation, embedding, polymerization, and sectioning at hig...
